数据中心研究(6):可用性和可靠性
Research on data centers (6): Reliability and availability
摘要：
阐述了可用性和可靠性的定义，介绍了可靠性和可用性的计算方法。以某工程为例，分别计算了传统数据中心和采用燃气冷热电三联供（CCHP）系统的数据中心的电源和供冷系统的可用性。结果表明，燃气CCHP适用于数据中心，有利于提高数据中心，尤其是大型、超大型数据中心的可用性。

Abstract：
Describes the definition of availability and reliability, and presents the calculation methods of reliability and availability. Taking a project as an example, compares the availability of the power supply and cooling system of the traditional data center with those of data center using gas CCHP system. The results show that gas CCHP is suitable for data centers and can enhance the availability of data centers, especially large and super large data centers.
